Definitions

• the invention relates generally to broadcast systems and, more specifically, to selecting relevant products to be transparently acquired via a consumer's set-top box coupled to a broadcast system.
• Broadcast systems traditionally transmit data in one direction from a server system to a plurality of client systems. Consumers ofthe client systems typically receive the signals from the server system as they are broadcast.
• One paradigm in which consumers are provided with explicitly selected content involves server systems that broadcast the same data continuously and/or at staggered intervals; such as, for example "pay per view” movies. "Pay per view” movies are available from cable or satellite television broadcasters that send the same movies repeatedly on multiple channels at staggered intervals. Consumers that wish to watch a particular movie simply tune in to one ofthe channels on which the desired movie is broadcast at a particular known broadcast time.

In addition, the consumer may have explicitly provided a rating of, for example, 9 out of 10 to Ms. Aniston.
• Figure 6 illustrates a flow of actions taken to select products to be transparently delivered to a consumer pursuant to one embodiment ofthe invention.
• the CPS evaluates each key/value pair ofthe meta-data within a group of packages, delivery schedule or availability list to determine whether the key/value pairs ofthe predictive vectors are included in the meta-data. For each ofthe packages or products listed in the schedule having at least one key/value pair that matches a predictive vector, a comparison is made between all key/value pairs ofthe package and all predictive vectors. A predictive preference level for the package is then determined based on the total number of matching predictive vectors, the total standard deviation, and the total reference magnitude ofthe package.
• the CPS obtains the meta-data for first package and sets it as the current package, as shown in block 610.
• the CPS then obtains the first key/value pair from the package meta-data and sets the current package pair, as shown in block 612.
• the CPS then obtains the first predictive vector from the list of predictive vectors and sets the current predictive vector, as shown in block 614.
• the CPS determines whether the current predictive vector matches the current package pair, as shown in block 616.
• the CPS determines the reference magnitude and the standard deviation for the current package by comparing all ofthe predictive vectors with all ofthe package pairs, and storing the total number of matching predictive vectors, the total standard deviation for all matching predictive vectors, and the total reference magnitude, as shown in block 618.
• the CPS determines the predicted preference level and the competence level ofthe current package and stores these values, as shown in block 620.
• the predicted preference level is determined by dividing the total reference magnitude by the total number of matching predictive vectors, such that the predicted preference level is the average reference magnitude of all matching predictive vectors.
• the competence level is determined by dividing the total standard deviation of all matching predictive vectors by the total number of matching predictive vectors, such that the competence level is the average standard deviation of all matching predictive vectors.
• the CPS may reside on the delivery center server.
• the CPS may determine consumer preferences both implicitly and/or explicitly based on information fed to the delivery center server from the client's set-top box.
• CPS on the delivery center server may execute the various embodiments ofthe invention described herein in the same way as if the CPS were located on the consumer's set-top box.
• CPS on the delivery center server may also use additional data to determine consumer's preferences, such as, for example, the consumer's billing records which, in one embodiment, may be maintained in a database at the delivery center server.
• CPS on the delivery center server may communicate with additional third party databases to obtain further consumer information linked to the street address and/or telephone number associated with the registration information or billing information associated with the consumer's set-top box.
• the delivery center server CPS may use this further data in determining the consumer's preferences.
• products tailored to the consumer's predicted tastes are transparently delivered to the consumer's set-top box.
